I am writing this review to warn future customers about my unacceptable experience with Affordable…read moreTransmission and Auto Repair Center regarding an ATRA nationwide warranty repair. Background and Initial Service: My vehicle's transmission was rebuilt a few months ago by a different authorized ATRA shop. Due to a recent move, the original shop authorized me to bring the car to this affiliate location, a 30-mile drive from my new home, for a warranty diagnosis. Upon drop-off on 11/18/2025, the front desk employee immediately became cold and dismissive when I mentioned the words "warranty repair." The Issue & The Refusal to Diagnose: The problem is specific and reproducible: when the car is cold, driving downhill causes the transmission to shift into what feels like neutral. Pressing the gas results in rising RPMs but no movement, forcing me to shut the engine off and restart it to re-engage the drive. After two days, I received a call informing me they could not reproduce the issue and were refusing to work on the car. I explained to Miguel that the condition requires a cold start and a specific downhill coast, asking them to try again or keep the car longer. He flatly refused any further testing, stating they were done with the vehicle. Integrity Violation and Fraudulent Documentation: Since they refused to honor the warranty, I requested a written reason for the denial of service, which is standard procedure. Miguel went to review my paperwork. When he returned, he presented a form and demanded I sign it before he would provide any written explanation. This form was an explicit waiver where I would acknowledge that the issue I claimed was not present and that their testing proved my claim was false. I refused to sign a document that was contrary to reality, as the transmission issue is demonstrably still present. The Threat and Escalation: Because I refused to sign the false waiver, Miguel refused to give me any written denial and escalated the situation. He told me he wouldn't help me anymore because I was "not a nice person." When I stated I would write an accurate review of this unprofessional experience, he raised his voice and began threatening me: Threats of litigation. Explicit threats of physical harm to myself and/or my property at my home. Threats to contact my employer to have me fired. I immediately took my keys and walked to my car, with Miguel following me out of the office, continuing to curse and issue threats. This behavior is far beyond poor customer service; it is menacing, unprofessional, and a direct failure to honor the ATRA warranty program. The shop refused to perform due diligence, attempted to force me to sign a false legal document, and threatened my physical safety. Avoid this business at all costs.

I'm updating my review because I was contacted by Robert, the owner, who kindly let me know that he…read moreunderstood my position and concerns. He was genuinely concerned about my negative experience and went above and beyond to make things right. That says an extraordinary amount about the pride he takes in his business and shows that he is an honest businessman who stands behind his work and customers. While the original situation was frustrating, I truly appreciate the effort and professionalism shown in resolving the matter. I believe it's important to update reviews when a business makes an effort to correct a problem, and in this case they absolutely followed through in the end. Thank you for doing the right thing and standing behind your customer.

They took a look at my car for free to identify the issue and they detected the leak to be coming from my engine and not my transmission. They showed me exactly what they were seeing, why they thought it was my engine and not my transmission, and offered to put a dye in my transmission fluid to ensure it was my engine and not my transmission. I drove my car for a week and took it back to double check, and sure enough it was my engine! Although they spent time and care on my car, they didn't charge me a single penny, even when I insisted to at least pay for the dye. They were able to refer me another mechanic to fix my engine leak and I was able to get my issue solved that same day. As a woman who is nervous to get work done on my car, I had an excellent time at El Monte Transmission. If you are having transmission troubles, please go to them :)

In the end up having to wait three days to get my vehicle To make matters worse, they failed to properly reconnect my oil dipstick to the engine block, which is a basic but critical oversight.
